The Rasch Foundation started the site you quoted with an express purpose of promoting plant-based diets. So, take their one-sided agenda into account when quoting their science.

From their website:

Created NutritionFacts.org in collaboration with Dr. Michael Greger, a leading expert on the impacts of nutrition on disease prevention. It has since become one of the largest non-profit healthcare sites on the Internet and a preeminent resource for consumers and physicians to learn about plant-based nutrition.
